Hard (surname)

Hard is a surname. Notable people with the surname include:

Hardcourt

A hardcourt (or hard court) is a surface or floor on which a sport is played, most usually in reference to tennis courts. They are typically made of rigid materials such as asphalt or concrete, and covered with acrylic material to seal the surface and mark the playing lines, while providing some cushioning. Historically, hardwood surfaces were also in use in indoor settings, similar to an indoor basketball court, but these are now rare.

Tennis

Tennis hard courts are made of synthetic/acrylic layers on top of a concrete or asphalt foundation and can vary in color. These courts tend to play medium-fast to fast because there is little energy absorption by the court, like in grass courts. The ball tends to bounce high and players are able to apply many types of spin during play. Flat balls are favored on hard courts because of the extremely quick play style. Speed of rebound after tennis balls bounce on hard courts is determined by how much sand is in the synthetic/acrylic layer placed on top of the asphalt foundation. More sand will result in a slower bounce due to more friction.

Premenstrual syndrome

Premenstrual syndrome (PMS) refers to physical and emotional symptoms that occur in the one to two weeks before a woman's period. Symptoms often vary between women and resolve around the start of bleeding. Common symptoms include acne, tender breasts, bloating, feeling tired, irritability, and mood changes. Often symptoms are present for around six days. A woman's pattern of symptoms may change over time. Symptoms do not occur during pregnancy or following menopause.

Diagnosis requires a consistent pattern of emotional and physical symptoms occurring after ovulation and before menstruation to a degree that interferes with normal life. Emotional symptoms must not be present during the initial part of the menstrual cycle. A daily list of symptoms over a few months may help in diagnosis. Other disorders that cause similar symptoms need to be excluded before a diagnosis is made.

The cause of PMS is unknown. Some symptoms may be worsened by a high-salt diet, alcohol, or caffeine. The underlying mechanism is believed to involve changes in hormone levels. Reducing salt, caffeine, and stress along with increasing exercise is typically all that is recommended in those with mild symptoms.Calcium and vitamin D supplementation may be useful in some. Anti-inflammatory drugs such as naproxen may help with physical symptoms. In those with more significant symptoms birth control pills or the diuretic spironolactone may be useful.

PMS1

PMS1 protein homolog 1 is a protein that in humans is encoded by the PMS1 gene.

Function

The protein encoded by this gene was identified by its homology to a yeast protein involved in DNA mismatch repair. A role for this protein in mismatch repair has not been proven. However, the protein forms heterodimers with MLH1, a DNA mismatch repair protein, and some cases of hereditary nonpolyposis colorectal cancer have been found to have mutations in this gene.
